MAX RUBIN, OF NEW YORK, Y.

STRAP-ADJUSTER.

Specification of Letters Patent.

Patented Apr. 4, 1916.

Application filed February 19, 1915. Serial No. 9,228.

To all whom it may concern:

Be it known that 1, MAX RUBIN, a citizen of the United States, and a resident of New York city, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Strap-Adjusters, of which the following is a specification.

This invention relates to strap adjusters. The object of my invention is to provide a new and improved strap adjuster for overalls and similar articles, which can be applied on the overall strap at the front end of the same after the strap has been secured to the overalls at the rear and after the same has been turned back on itself at the front to form a loop for the eye, which serves to receive the front button on the overalls, which improved strap adjuster requires no sewing while applying the adjuster. Overall suspenders are made either integral with the overall which is called high-back and also separate suspenders which are attached in the back by a button to the overall. The separate straps on the back of overalls are made with heavy elastie and must be adjusted to the buckle as hereinafter described.

In the accompanying drawings in which like letters of reference indicate like parts in all the figures: Figure 1 is a front view of my improved strap adjuster. Fig. 2 is a plan view-of the same. Fig. 3 is a longitudinal sectional view on the line aa of Fig. 1. Fig. 1 is a view of the upper part of the overalls with the strap. Fig. 5 is a detail view showing the strap in longitudinal section and the strap adjuster secured Fig. 6 is a perspective view of the pocket on the end of the strap;

My improved strap adjuster consists of an open frame 1 which is flanged at the sides, top and bottom as indicated at 2. From the side members 3 of the frame, two tongues 4 project inward and toward each other and are separated at their inner end about one quarter of an inch more or less. The tongues as shown in Fig. 2 project from the inner edges of the side members 3 and are curved about to the plane of the teeth on the top flan e 5 and their ends are rounded so as to facilitate slipping the straps of the overalls upon them. The curved tongues a are provided on their upper edge, if desired, with one or more teeth 6, which are preferably inclined from the free ends of the tongues toward the fixed ends.

The upper flange 5 of the frame is made deeper than the flanges on the sides and ends and is provided with teeth 7 on its free edge. The frame 1 is flanged at the ends because it is seized with the fingers at these ends in moving it up and down on the strap or webbing and the flange are provided for presenting a proper bearing for the fingers, so that the same need not be 'pressed against the edges of the metal,

which would be apt to cut the fingers-as the metal is thin. The rearwardly extending end flanges give a good bearing and further more cause the frame to project So far toward the front of the strap that the fingers can seize and grasp it easily. They also serve to strengthen and stiffen the frame.

Overalls, a part of which is represented at 8 are provided with shoulder straps 9 which are secured to the overalls at the back as represented at 10 and at the front, the overalls are provided with a button represented at 11 upon which an eye 12 is applied, which is mounted slidably on the front of the strap, which for this purpose is doubled over to form a loop13. The strap adjuster is applied on the free end of the shoulder strap and is adapted to he slid up and down on the strap for the purpose of Shortening and lengthening the same. The strap adjuster is not secured to the strap by sewing when the adjuster is on the strap but is applied on the strap. after the strap has been completed. For this purpose the free end of the strap is provided, with a loop 14 which is .open at the ends.

The strap adjuster as stated is not sewed to the strap 9 but nevertheless must be held upon the same. following manner: The shoulder strap at a point somedistance from the free end is crowded together, that is, the side edges are pressed together so as to reduce the width of the strap so that this strap can pass in between the free ends of the tongues 4 from the rear and then it is widened out to its normal width in front of the tongues L and behind the frame 1 in such a manner that it can slide up and down onthe strap and so that the frame will be at the front of the I accomplish this in the strap. Then the end of the strap provided with the loop 14 is doubled over rearward to form the loop 13 for holding the spring eye 12 and the free end of the strap provided with the loop 14 is placed on the back 4 of the frame, and one of the tongues 4 is slipped into one open end of the loop 14. Then the remaining portion of the loop is puckered or crowded together so that the other tongue can be passed into the other open end of the loop and the loop 14 slipped on the other tongue and that part of the strap inwhich the loop is formed is brought back to normal width. The two tongues will thus project into the oppos'te ends of the loop and this loop is held on the adjuster back of that part of the strap which has been previously placed into the frame. If new the frame is seized between the fingers by grasping the ends of the frame, the frame can be slid up and down on the webbing or strap so that the effective length is decreased As soon i or increased as may be desired. as tension is brought upon the strap and the frame is released, the strap is pressed against the teeth 7 on the back of the top member of the frame, which teeth are I pressed against the fabric of the strap and 7 position.

thus prevent movement of the frame on the strap but as soon as the tension on the strap ceases, thenframe can be grasped between the fingers and readily brought toa new In order to prevent the loop 14 from being drawn or slipping through the opening between the tongues 4 and to prevent puckering and creeping of the pocket toward the space between the tongues 4, I have preferably provided a reversely inclined tooth 6 on each tongue 4, said tooth formed in the flange on the top edge of the strap adjuster and does not depend on the friction between the loop on the tongues and that part of the strap-v which is passed over the loop 14 within the frame 1.

I am aware that there arebuckles made with, integral tongues and slots, but in my buckle the tongues are stamped out from the inside of the frame and in threading the web, on to my buckle this is done en-.

t rely between the tongues and the back of the frame and no threading at all is done through the slots from the rear to the front of the frame, or vice versa.

Having described my invention what I claim as new and desire to secure by Letters Patent is 1. A strap adjuster comprising a quadrilateral metal frame having at its top edge a longitudinal rearwardly projecting flange,

teeth formed on and projecting from .the edge of said flange, two tongues located intermediate of the top and bottom bars of the frame and projecting from the =end-i pieces of the frame toward each other, but

separated from each other at their free ends and bent out of the plane of the frame; the

teeth of said longitudinal flange and the two tongues having such relative positions that the front portion of a doubled strap will, while under tension, be secured by the teeth of said longitudinal flange.

2. A strap adjustercomprising a metal.

frame-having at its top edge a longitudinal rearwardly projecting flange, teeth formed on and projecting, from the edge of: said flange, two tongues located intermediate of the top and bottom barsof the frame-and projecting from the end pieces of the frame toward each other, but separated from each.-

other, at their free ends and bent out ofthe plane of the frame, and teeth on the upper edges. of the tongues for engaging the strap a to insure it against slipping widthwise, the

teeth of said longitudinal flange and the two tongues having such relative positionsthat the front portion of; a doubled strap While under tension will be secured by the teeth of said longitudinal flange.

3. A strap adjuster comprising a metalyl frame having at its top edge a longitudinal rearwardly projecting flange, teeth formed on and projecting from the edge of said flange, two tongues projecting from the end pieces of the frame toward each other, but. separated from each other at their free ends,

and teeth extending from the upper edges of the tongues for engaging the strap to insure it against slipping, widthwise, inclined from the free ends ofthe tongues to-:

ward the fixed end so that these teeth will not interfere with. slipping the strap upon the tongues from the free ends toward the 1 fixed ends of the tongues, the-teeth of said-rv longitudinal flange andthetwo tongues having such relative positions that the front portion of adoubled strap, while under ten-i sion, will be secured iby the teeth of'said,

longitudinal flange.
